PKI-166 hydrochloride is a potent, selective and orally bioavailable EGFR tyrosine kinase inhibitor, with an IC50 of 0.7 nM[1].

IC50 & Target

IC50: 0.7 nM (EGFR tyrosine kinase)[1]

In Vitro

Pretreatment with PKI-166 hydrochloride (0-0.5 μM; 1 hour) inhibits EGFR autophosphorylation in human pancreatic cancer cells[1].
PKI-166 hydrochloride (0.03 μM; 6 days) enhances the cytotoxicity mediated by gemcitabine[1].

Western Blot Analysis[1]

Cell Line: L3.6pl cells
Concentration: 0.01 μM, 0.05 μM, 0.5 μM
Incubation Time: 1 hour
Result: Inhibited EGFR autophosphorylation in a dose-dependent manner.

Cell Cytotoxicity Assay[1]

Cell Line: L3.6pl cells
Concentration: 0.03 μM
Incubation Time: 6 days
Result: Enhanced the cytotoxicity mediated by gemcitabine.
In Vivo

PKI-166 hydrochloride (100 mg/kg; p.o.; daily; day 7-day 35 after xenograft) inhibits of pancreatic cancer growth[1].

Animal Model: Male athymic nude mice with L3.6pl cells xenograft (8–12 weeks)[1]
Dosage: 100 mg/kg
Administration: Oral administration; daily; from day 7 to day 35 after xenograft
Result: Significantly decreased median tumor volume.
